## Overview

A small interactive C++ calculator: the user selects an operation, enters values through the console, and receives a printed result. The single source file implements arithmetic, power, roots, trigonometry, logarithms, and two derivative approaches. The operation nodes represent branches within `main`, not separate modules; the derivative estimate additionally calls `f`.

Main entry points: [`simple_calculator.cpp`](https://github.com/faridacherifch-source/simple-calculator/blob/main/simple_calculator.cpp) (Menu loop)
